T 0 all whom it may concern.

.Be it known that I, NiLs W. Kaunrrz, a subject'ot the King of Sweden, residing at Hoquiam, in the county of Chehalis and State of \Vashington, have invented certain new and useful Improvements in Brake- Equalizers, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to vehicle brakes to automobile brakes wherein brake hands or shoes operate on wheels onopposite sides of the vehicle, and an object or" this invention is to provide an equalizing device for the brake members which will permit an equal and positive pressure tothe members, and operate them simultaneously, even though theadjustment of the leverage of the members may not be; the same.

With this and other objects in view, the invention comprises certain features of construction which will be hereinafter more fully described and which are illustrated in the accompanyingdrawings, in which,

Figure 1 is a plan view of the equalizing member showing it secured to the frame of a vehicle. Fig. 2 is a section taken on the line 2 I 2, of Fig. 1. Fig. 3 is a detail section of the equalizing member, and, Fig. 4

is a section taken on the line &4,' of Fig. 3.

Referring to the drawings by characters of reference, the numeral .1 designates the frame of a vehicle, of which 2 are the drive wheels. A lever 3 is secured to the vehicle I near the front portion thereof, one end of mounted rack bars 8 which are supported.

on opposite sides of the wheel 6 in guideways 9, are adapted to mesh with the spur wheel of This wheel is held in position in the frame by means of a washer 10 which is secured ttimthe frame means of a bolt Speeificatiouof Letters Patent.

11 and nut 12, the bolt 11 also providing an axle for the wheel to revolve upon. Se cured vto the rack bars 8, are rods 13 which are pivotally connected to collars 14 which are secured to a hollow shaft 15 which is in two sections working independently of each other; The opposite ends of the hollow shaft members 15 extend through the frame or" the vehicle and rotate inbea-rings 16 having collars 17 secured to their eX- t-remities which are connected to rods 18 which lead to the contracting brake bands (not shown). v

A duplicate equalizing member A is supported on one side of the frame of the veicle, one endof which is secured to a rod 19 leading to an emergency brake lever (not shown) and having one of the rack bars 8 secured to a rod 20 which leads directly to an expanding brake band (not shown). The other rack bar 8 is connected to a rod 21 which is pivotally secured to a collar 22 which is mounted on a shaft 23 which extends through the hollow shaft 15 Where it is pivotally secured to a rod 24 which leads to a corresponding expanding brake band (not shown).

The operation of my device is as follows: When power is applied to either or both of the brake operating levers, the equalizing frame is reciprocated and the power is transmitted therefrom to the brakes. Should the connections to the brakes have the same tension, the spur wheel will not retate when. power is applied, but should the levers of one of the connections be loose, the wheel will rotate and take up the slack on the rack that is loose and pay it out on the other, thereby equalizing the tension of the rod and applying the power to both brakes simultaneously.

Having thus described my invention what I claim and desire to secure by Letters Patent is In a brake equalizer, a reciprocatory frame having an apertured extension on one end, a brake operating lever secured in-the apertured extension, a spur wheel revoluloly formed with p opposite sides o the sa1d'seejt,-'saclt here m omml connected at one end :0 the brakes and the In testimony-whereof I hereunto eiiix' my other ends theme; slidably mounted in the signature in the presence of two witnesses. channels in the tame. and meshing with T 1; r e the spur Wheel, and a bolt adapted to seh-AULHTL cure the said cover plate to the frame and Witnesses:
